The value of the variable dc doesn’t change in my code. I’ve tried debugging it but it’s still never changing. I’m new to C++ coding. What am I doing wrong, and how can I solve the problem? From what I know: It should change whenever I iterate because fd changes every time I complete a ..

int main() { int a=5,b=-7,c=0,d; d= ++a && ++b || c++; cout<<a<<"t"<<b<<"t"<<c<<"t"<<d<<"n"; int x = 1,y =0,z=5; int e = x&&y||z++; cout<<x<<"t"<<y<<"t"<<z<<"t"<<e<<"n"; int f = x&&y&&z++; cout<<x<<"t"<<y<<"t"<<z<<"t"<<f<<"n"; int g = x&& y&& ++z; cout<<x<<"t"<<y<<"t"<<z<<"t"<<g<<"n"; int h = x&& y|| ++z; cout<<x<<"t"<<y<<"t"<<z<<"t"<<h; return 0; } //***OUTPUT*** // 6 -6 0 1 // 1 0 6 1 ..

I’m a beginner in programming, and in one of the exercises in a course I’m taking, I came across the weird result shown above. I’m working on Windows and using Python 3, and I got the same result on Jupyter Notebook as well as Pycharm. I tried to find an explanation for this online, but ..

The program is meant to convert a USD($) quantity inputted by the user (from $0 to $10 max) and output it in quantities of quarters, dimes, nickles, and pennies. #include <iostream> const double QUARTER {0.25}; const double DIME {0.10}; const double NICKLE {0.05}; const double PENNY {0.01}; void dollarToCoin(double cash, unsigned short& quarters, unsigned short& ..

I was trying to solve this exercise: https://www.codeabbey.com/index/task_view/fahrenheit-celsius However, here is the solution: #include <iostream> using std::cout; using std::cin; int main() { int n, a; cin >> n; int* answers = new int[n]; // allocating memory for (int i = 0; i < n; i++) { cin >> a; answers[i] = (a – 32) * ..

I’m trying to make a specific combination so that it adds up to "4" by adding the following specs: a+a+a+a+a+a+a+a = 0.5 per/unit = (In total it sum:) 4 b+b+b+b = 1 per/unit = (In total it sum:) 4 c+c = 2 per/unit = (In total it sum:) 4 That way I want to know ..

If a user enters a number "n" (integer) not equal to 0, my program should check if the the fraction 1/n has infinite or finite number of digits after the decimal sign. For example: for n=2 we have 1/2=0.5, therefore we have 1 digit after the decimal point. My first solution to this problem was ..

I wonder, why functional objects in c++ are implemented as templated, with void as default type since c++14. For example: https://en.cppreference.com/w/cpp/utility/functional/plus https://en.cppreference.com/w/cpp/utility/functional/minus This object in fact performs arithmetic operation +, -, *, /, when called by operator(). The operator() has to be template to work with different types as arguments, but why does the struct ..
